| Total time | 7h21 | 7h01 | 20 min · 220i Gran Coupe F44 |

| Cost of energy used | 454.07 € | 84.09 € | 369.98 € · 220i Gran Coupe F44 |
Both vehicles drove at 130 km/h for the entire trip. The gap is built at the stops: no stop for the 220i Gran Coupe F44 versus 4 stops totalling 20 min for the Boxster Spyder.
The official WLTP figures (10,7 L/100km for Boxster Spyder and 5,7 L/100km for 220i Gran Coupe F44) are measured on a mixed cycle averaging ~46 km/h. At a steady 130 km/h, aerodynamic drag weighs much more heavily - it grows with the square of speed. Caralogy calculates a motorway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve - not a uniform correction factor. For this trip, the simulation yields 27,0 L/100km (Boxster Spyder) and 5,0 L/100km (220i Gran Coupe F44). Full methodology: see the assumptions below the controls.

On Paris → Marseille (775 km at 130 km/h), the 220i Gran Coupe F44 arrives in 7h01 with 0 fuel stops.
WLTP consumption does not reflect motorway reality. Aerodynamic drag grows with the square of speed, so real consumption is 15 to 25 % higher than WLTP combined. Caralogy calculates a highway consumption specific to each vehicle based on its aerodynamic profile (SCx), weight and power curve.
Total time = driving time + charging time. Driving time is calculated at an average speed of 130 km/h on the motorway (adjustable). Charging time is calculated based on the real power curve of each vehicle, respecting the optimal 10 → 80 % range and the maximum power accepted by the chargers on the route.
No. The displayed cost covers only the energy consumed during the trip: kWh × energy rate, with a mix of home charging and DC fast chargers. Battery wear is a long-term ownership cost, not a trip cost.
On this trip, the energy used costs 454.07 € (Boxster Spyder) and 84.09 € (220i Gran Coupe F44). For reference, an equivalent BMW M340i (~9.5 L/100 km) would cost about 136 € in fuel.
